SCRUBBING AND DRYING MACHINE.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, ARTHUR E. HAUCK, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, coun y of Kings, and State of New York, have invented a new and useful Improvement in Scrubbing and Drying Machines, of which the following is a specification.

The object of my invention is to provide a machine of this class which may be used for scrubbing a floor with an endless mop cloth that automatically cleans the dirty water out of the mop cloth and supplies the same with fresh water, or absorbs water from a moist floor. These, and other objects are accomplished by my invention, one embodiment of which is hereinafter set forth.

For a more particular description of my invention, reference is to be had to the accompanying drawings, forming a part hereof, in Which Figure 1 is a side elevation of my improved machine. Fig. 2 is a longitudinal section of the same, taken on the line 22 of Fig. 4, looking in the direction of the arrows. Fig. 3 is a sectionai view, taken on the line 33 of Fig. 1, looking in the direction of the arrows. Fig. 4 is an end elevation of my improved machine. Fi 5 is an enlarged view of a portion 0 the structure shown in Fig. 3. Fig. 6 is a reversed plan view of the structure shown in Fig. Fig. 7 is a sectional view, taken on the line 77 of Fig. 5, looking in the direction of the arrows.

Throughout the various ,views of the drawings, similar reference characters designate similar parts.

My machine 1 is provided with a suitable frame 2 which is composed of suitable rectangular side frames 3 united by suitable crossings 4, which hold all parts of the frame 2 in proper relation, one to another.

At each corner of the frame are mounted suitable rollers 5, 6, 7 and 8 over which runs the endless mop cloth 0 ebbing9, as shown. The upper middle run of this webbing 9 is between the wringing rollers 10 and 11 which will be described below, and these rollers may be adjusted to force the webbing below the surface of water, or other suitable liquid, in the tank or trough 12, which is carried on the frame 2.

The roller 6 runs idle and supports one end of the frame 2 and rests on the lower run of the webbing 9. This roller 6 is made in any suitable way, and is preferably mounted with a suitable pivot 13 in each side frame 3. The roller 5 is larger than the roller 6 and has suitable bearings 14.- and a ratchet 15 fixed thereon which ratchet is engaged by a spring pressed pawl. 16 mounted in a side frame 3 so as to permit the roller to run in one direction only, say clockwise. This roller 5 is provided with suitable suction pockets 17 placed on its periphery so as to give it better traction and to cause it to shift the webbing 9 to better advantage.

The rollers 7 and 8 have suitable spina 18 which are mounted in abile vii-hes ii and extended sufficiently to .L between the guides 20 which rise from each upper corner of each side frame The y s 19 are suit ably supported from cross g i suitable coil springs 21 which r-...t on adjusting: screws 22 which are set in the bracket 4 The springs 21 rest in suitable pockets 23 which are provided for the purpose on the yokes 19. It is apparent that the function of these springs 21 and the adjusting screws 22 is to keep the endless mop cloth or webbing 9 in proper tension.

The tank or trough 12 is provided with a suitable handle 24, and the machine 1 is operator. by the aid of a handle 2-5 which has a suitable bail 26 which runs to ears 2'? at top and center of each side frame 3. At the cen ter and top of each side frame 3 and running laterally thereof and vertically, is a guide 28 which guides are connected by a suitable yoke 29 and the lower arms of the yoke 29 are united by the spindle 30 on which the roller 11 is mounted. Above this roller is the webbing 9, as above described, and above this is a second roller 10 which has a suitable spindle 31 which engages a suitable yoke 32, which has flanges 33 which engage the vertical arms on the yoke 29 so that the roller 10 runs on the cloth 9, and may be adjusted vertically with regard to same and the roller 11. The yoke 29 also has suitable flanges 34 at each end which enter suitable recesses formed by the turned over edges 35 of the guide 28 so that the yoke 29 and its connected parts are properly guided at all times.

The yoke 29 is fixed at any desired elevation by means of suitable rack bars 36 which are fixed to the guides 28 and at one side thereof and parallel therewith, and these webbing 9 always .60

bars are engaged by suitable carried by suitable brackets downwardly in a diagonal direction from the top bar of the yoke 29 and also by a bracket 39 which runs laterally of the top bar of the yoke 29 and through which passes a vertical spindle {0, which is secured to the center member 41 of the bolts 37. The ver tical spindle 40 carries a cross-bar or handle 42 at its top by means of which it may be raised so that the bolts 37 occupy the position shown by the dotted lines in Fig. 5 when they are withdrawn from the rack bars 36. To facilitate the manipulation of the bolts, through the handle 42. a larger handle 43 is carried from extensions 44 of the bracket 38. The larger handle 43, which is supported from the bracket 38, as shown in Figs. 1 and 3, is so placed that the hand of a person may easily grasp it and then his fingers may be extended far enough to grasp the handle 42 and raise the same. and thereby withdraw the bolts 37 from the racks 36 with which they normally engage, and then the rollers 10 and 11 may be raised and lowered as desired. The spring 46 normally tends to keep these rollers together, as will be readily understood.

The roller 10 is kept in proper relation with the roller 11 by means of a suitable spindle 45 and a spring 46 mounted thereon, together with a wing-screw 47 mounted on the spindle 45. The wing-screw 47 has threads on its exterior which engage corre sponding threads in the top of the yoke 29, so that by turning this screw 47, any suitable tension may be placed on the spring 46, and this will cause the roller 10 to press against the webbing 9 in a suitable manner, because the spindle 45 is fixed to the yoke 32 in which this roller is mounted.

In view of the foregoing, the operation of my improved machine will be readily understood. Assuming that it is to be operated to clean a floor, not to dry the same, the wing-screw 47 is turned, if necessary, and the bolts 37 are shifted until the rollers 10 and 11 are so placed that the webbing 9 runs under the upper surface of the water. he machine is then trundled over the floor and shoved backward and forward by means of the handle 25, the weight of the machine being carried by the rollers 5 and 6 which run on the webbing 9, when the roller 6 is the forward roller, and when the roller 5 is the forward roller, the pawl 16 prevents the turning of this roller so that the webbing 9 cannot be shifted. The result is that the moves in a clockwise direction and not otherwise with regard to the rollers against which it bears, so that it is always shifted in the same direction, through the rollers 10 and 11, which are wringing rollers. As the webbing 9 enters the rollers 10 and 11 it is squeezed and the soiled water spring bolts 37 38 which bend squeezed out, and when this webbing emerges from these rollers it is saturated with cleaner water which in due time reaches the floor, so that the mop cloth automatically cleanses itself and cleans the floor. \Vhen the machine is used for drying purposes, the rollers 10 and 11 and webbing are removed out of the water and then the machine is used as before. except that the wringing rollers serve to take out the dirt Y water and no water is supplied thereafter to the webbing 9 until the same reaches the floor and absorbs the moisture which is taken up in the drying process.

\Vhile I have shown and described one embodiment of my invention, it is obvious that it is not restricted thereto, but is broad enough to cover all structures that come within the scope of the annexed claims.
